如何触发JavaScript事件触发器？

Question

I have an input using a onkeypress trigger, and I'm trying to find a way to fire the event trigger with a specific keycode. I've looked around but all I find are jQuery solutions, and I don't want to use jQuery.

For a click trigger you'd just use document.forms[0].elements[1].click() but there doesn't seem to be a keypress() equivalent for onkeypress .

You can create an event and dispatch it to your Object. just like this:

if(document.createEvent) { 
  var evObj = document.createEvent('KeyEvent'); 
  evObj.initEvent( 'keypress', true, false); 
  evObj.keyCode = 13; // Set your keyCode
  document.getElementById("myid").dispatchEvent(evObj); 
}

under IE/FF:

var evObj = document.createEventObject();
evnObj.keyCode = 13;
document.getElementById("myid").fireEvent("onclick",evObj);
event.cancelBubble = true;
